3.2.1. Serializer Bypass for DDR and SDR Operations
The I/O element (IOE) contains two data output registers. Each data output register can operate in double data rate (DDR) or single data rate (SDR) mode. Use the GPIO Intel® FPGA IP to bypass the serializer and operate in DDR and SDR modes.
Figure 5. Serializer BypassThis figure shows the serializer bypass path.
